Penned by MG Designer Syd Enever, the MGA was “the first of a new line” of MG’s to come out following the TD chassis. The seats are slung lower, due to the floor being attached to the bottom of the frame sections, opposed to the top as they had been previously. The MGA repaired falling traditional MG model sales upon its initial release. Previous models of the MGA were powered by a fairly low-compression 68 horsepower inline four-cylinder. In 1958 the high performance Twin-Cam was added. It had a high-compression DOHC aluminum head that delivered 108 horsepower. The cars were also fitted with Dunlop four-wheel disc brakes, a huge improvement over the four-wheel drums of earlier MGA’s. The Twin-Cam came with knock-off steel wheels that were unique to the model. Those wheels and a small logo near the vent were the only distinguishers of this Twin-Cam model. Top speed was found to be 113 mph and 0-60 could be accomplished in 13.3 seconds.
